Benefits of technology
The present invention provides a method of transmitting mobile services that can flexibly respond to changes in a mobile broadcasting system while processing a partial region of a data group to be compatible with the conventional mobile broadcasting system or the entire region of a data group to be used for a new mobile broadcasting system. Additionally, the transmission system inserts mobile service data and known data into a conventional mobile service data area to enhance the reception performance of the mobile service data at the reception system. The transmission system also forms continuous known data sequences by interconnecting discontinuous known data and generates information of additional mobile service data to smoothly communicate with the reception system.
Problems solved by technology
Therefore, the receiving performance of the digital broadcast receiving system may be deteriorated in a poor channel environment.
Particularly, since resistance to changes in channels and noise is more highly required when using portable and / or mobile broadcast receivers, the receiving performance may be even more deteriorated when transmitting mobile service data by the VSB transmission mode.

The disclosed method of processing a digital broadcast signal comprises generating one RS frame or two RS frames according to the RS frame mode, forming the data group including the mobile service data and signaling data, forming and outputting a plurality of data packets including the mobile service data in the data group, wherein the 118 data packets and K data packets are outputted for the data group, the K being scalable between 0 and 38, interleaving the mobile service data included in the plurality of data packets, wherein the data group includes a scalable data region including data included in the K data packets, wherein the scalable data region carries data included in the first RS frame when the RS frame mode is the single frame mode, or carries data included in the third RS frame when the RS frame mode is the dual frame mode.
Description
[0001]Pursuant to 35 U.S.C.§119(e), this application claims the benefit of U.S. Provisional Application No. 61 / 298,920 filed on Jan. 28, 2010, which is hereby incorporated by reference as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]1. The Field of the Invention[0003]The present invention relates to a digital broadcasting system for transmitting and receiving a digital broadcast signal, and more particularly, to a transmitting system for processing and transmitting the digital broadcast signal, and a method of processing data in the transmitting system and the receiving system.[0004]2. Description of the Related Art[0005]The Vestigial Sideband (VSB) transmission mode, which is adopted as the standard for digital broadcasting in North America and the Republic of Korea, is a system using a single carrier method. Therefore, the receiving performance of the digital broadcast receiving system may be deteriorated in a poor channel environment. Particularly, since resistance ...
